In this study, two types of CdSe, including nanoparticles and quantum dots, were synthesized. CdSe quantum dot nanoparticles were prepared via the hydrothermal technique at 140 °C for 8 h. The prepared CdSe materials were used as fluorimetric sensors aimed at the simultaneous analysis and detection of methamphetamine (Metha) as well as carbamazepine (Carba) drugs. Besides, the fluorimetric sensor was assembled depending on molecularly imprinted polymer (MIP) films with two sizes of cadmium selenide quantum dots as fluorophores source. The mechanistic synthesis of the fluorimetric sensor was based on covering the CdSe quantum dot nanoparticle surfaces with MIP film; afterward, a mixture of powdered yellow-CdSe@MIPs (y-CdSe@MIPs) and red-CdSe@MIPs (r-CdSe@MIPs) nanocomposites was applied for the simultaneous optical determination of Metha and Carba. Under optimal conditions, detection limits (DL) of 0.15 and 0.2 nM, as well as linear dynamic ranges (LDR) of 0.5 and 260 nM were acquired for Metha and Carba, respectively. Additionally, the application of the offered optical dual sensor was studied in human blood plasma as well as urine analytes.

Quantum dot-sensitized solar cells (QDSSCs) are significant energy-producing devices due to their remarkable capability to growing sunshine and produce many electrons/ holes pairs, easy manufacturing, and low cost. However, their power conversion efficiency (4%) is usually worse than that of dye-sensitized solar cells (� 12%); this is mainly due to their narrow absorption areas and the charge recombination happening at the quantum dot/electrolyte and TiO 2 /electrolyte interfaces. Thus, to raise the power conversion efficiency of QDSSC, new counter electrodes, working electrodes, sensitizers, and electrolytes are required. CdSe thin films have shown great potential for use in photodetectors, solar cells, biosensors, light-emitting diodes, and biomedical imaging systems. This article reviews the CdSe nanomaterials that have been recently used in QDSSCs as sensitizers. Their size, design, morphology, and density all noticeably influence the electron injection efficiency and light-harvesting capacity of these devices. A detailed overview of the development of QDSSCs is presented, including their basic principles, the synthesis methods for their CdSe quantum dots, and the device fabrication processes. Finally, the challenges and opportunities of realizing high-performance CdSe QDSSCs are discussed and some future directions are suggested.
